Thank you :-)

Anything convenient to you would be fine.

If we can somehow tag the whole branch, it would be most convenient.
Git can add description to a branch with

        git branch --edit-description [branch name]

However I don't know how to retrieve that description on a remote
branch..

Thanks,

The branch description is designed to be a place you leave your
temporary note locally outside the history, until you are ready to
set the contents of the branch in more permanent storage (e.g. by
merging it to an integration branch, or sending pull requests for
it) at which time the information is consumed (e.g. inserted in the
merge commit message or pull request message).  The history exchange
via "git push" / "git fetch" is by definition about exchanging the
history, and will not transfer branch descriptions.

For shared and more permanent notes, "git notes" may be more
suitable vehicle.

Great, let's settle with the in-commit tag "Dont-Auto-Build" for now :)

"git branch --edit-description" could potentially be the most elegant
solution, unfortunately for now there seems no way for me to retrieve
the branch description edited by you..

Another alternative, git tag, has the problem that it goes out of sync
every time you do rebase, which will sure happen a lot for early RFC
patches.

Commit notes or a special namespace for branches (refs/heads/wip/...) would
also be an option.
